Going on summer holidays and wondering which clever place to keep your spare house key while you are gone? For a relatively small price of under 10 dollars you could buy one of those fake rocks with a key compartment hidden in its underside. But a fake rock tends to look like a fake rock and leaves you wondering if it's acting like some sort of beacon to onlookers who are up to no good.

Why not use a real rock? One from your very own garden is bound to fit in. Pop over to Zakka Life to find out what to do with your old prescription bottle, some heavy-duty glue and an inconspicuous rock. Or even use some other item that is readily found in your yard, such as one commenter suggested, a large pine cone.
